Simulating quasar microlensing light curves: High magnification events
Favio Neira, Timo Anguita, Georgios Vernardos
Quasar microlensing can be used to constrain important astrophysical properties, such as the accretion disk size and the amount of stars in the lensing galaxy. The associated brigh…
The Very Knotty Lenser: exploring the role of regularization in source and potential reconstructions using Gaussian Process Regression
Georgios Vernardos, Leon V. E. Koopmans
Reconstructing lens potentials and lensed sources can easily become an underconstrained problem, even when the degrees of freedom are low, due to degeneracies, particularly when po…
Microlensing flux ratio predictions for Euclid
Georgios Vernardos
Quasar microlensing flux ratios are used to unveil properties of the lenses in large collections of lensed quasars, like the ones expected to be produced by the Euclid survey. This…
A joint microlensing analysis of lensing mass and accretion disc models
Georgios Vernardos
Microlensing of multiply imaged quasars is a unique probe of quasar structure, down to the size of the accretion disc and the central black hole. Flux ratios between close pairs of…
HST imaging of four gravitationally lensed quasars
Nicholas F. Bate, Georgios Vernardos, Matthew J. O'Dowd +7
We present new HST WFPC3 imaging of four gravitationally lensed quasars: MG 0414+0534; RXJ 0911+0551; B 1422+231; WFI J2026-4536. In three of these systems we detect wavelength-dep…
